Yeast infection

These things are the absolute WORST.... I’ve tried getting in contact with my gyn but she isn’t in the office. I’ve had this yeast infection since Tuesday of last week and nothing is helping at all I even told the lady who answers the phone my symptoms I asked her if I can see another gyn that works there and she had an attitude and told me there all busy and to continue to use monistat.... and I’m very uncomfortable and I start my cycle 2 days from now and today I noticed I’m swollen down there on one side and I honestly don’t know what to do anymore .
